CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 430,460, dated June 17,1890.

Application filed January 29, 1890. serial No. 338,473. (No model.)

State of Colorado, have invented certainnewand useful Improvements inOar-Couplings, of which the following is aspecification, reference beinghad therein to the accompanyin g drawin This invention relates tocertain improvements in car-couplings; and itconsists of the novelconstruction and combination of parts, as will appear from the followingdescription and accompanying drawings, in which- Figure 1 is a plan viewof my coupling in use, parts being broken away. Fig. 2 is a horizontalsection thereof. Fig. 3 is a front elevation of the same. Fig. 4 is adetail perspective view of the lever, and Fig. 5 is a horizontal sectionshowing my coupling uncoupled.

In carrying out my invention I provide a head or casting A, which isapproximately U-shaped and provided with a shank or stem portion a,having an aperture 1). This apertured shank or stem portion in practicebeing adapted to engage the link-chamber of the draw-head of theordinary form of car-coupling, provides, consequently, for the readyapplication of my coupling thereto, the aperture 1) serving to receivethe ordinary couplingpin, which, therefore, connects the two drawheadstogether.

B is the coupling-hook, which is approximately right-angled in shape andpivoted at its angle in one of the arms of the draw-head A, said armbeing bifurcated or slotted toreceive said hook. This hook engages inthe coupling operation, its counterpart being on a duplicate head orcasting.

O is a lever, which is lmuckle-jointed or pivoted to the inner end ofthe hook B and normally rests in a transverse groove or slot 0 in thehead or casting A, its outer end projecting through one arm of saidcasting within convenient reach for manipulation in ctfecting theuncoupling operation. The lever Chas at its lower edge a short distancei11- ward from its outer end a shoulder (I, which engages a stop 6,provided upon the casting or head A, immediately at one side of theplane of the slot or groove 0, to effect the securement of said lever ina locked position,

retaining the hook in its engaging orcoupled 6, which will permit thelever to be drawn outward, by doing which the coupling-hook B is thrownoutward when disengagement thereof from its fellow hook is permitted,and consequently the uncoupling of the cars. The opposite manipulationof said parts effects the coupling of the ears.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent. is-

1. In a car-coupling, the coupling-hook hung at its angle and having itsinner end recessed, in combination with the couplinglever pivoted at oneend in the slot of the coupling-hook, substantially as shown anddescribed.

2. In a car-coupling, the coupling-hook hung at its angle and having itsinner end recessed, in combination with the couplinglever pivoted at oneend in the recess of the coupling-hook and having a shoulder on itsunder side which engages a stop, substantially as shown and described.

3. In a car-coupling, the coupling-hook hung at its angle in abifurcation in the draw-head and having its inner end recessed, incombination with the coupling-lever pivoted at one end in the recess ofthe couplinghook and having ashoulder on its under side designed toengage a stop in a recess in theback of the draw-head, the lever incontinuation being projected through an opening in the side of thedraw-head which serves as a guide, substantially as shown and described.

4. In a car-coupling the coupling-hook pivoted at its angle, the leverconnected thereto in a slot or bifurcation of the drawhead and having ashoulder on its under side engaging the stop in said slot, substantiallyas shown and described.

5. The car-coupling having the swinging coupling-hook hung in thedraw-head and having the uncoupling-lever provided witha side of thecars, substantially as shown and I0 shoulder engaging a stop on thedraw-head, described. substantially as shown and described. In testimonywhereof I affix my signature 6. The car-coupling having the swinging inpresence of two Witnesses. 5 coupling-hook provided with theuncouplinglever'knuckle-jointed or pivoted to said hook, AARON B. ALLEN.and provided with a shoulder engaginga stop WVitnesses:

on the draw-heed and projecting through the CHARLES V. STICKNEY,

latter to permit its manipulation from the A. E. COLBURN.
